Endometriosis of the posterior cul-de-sac, unspecified depth

This code signifies the presence of endometrial-like tissue located in the posterior cul-de-sac (Pouch of Douglas), a common site for endometriosis. This specific code is used when the depth of infiltration of the endometrial implants into the cul-de-sac tissue is not specified in the medical record.

Apply this code when documentation confirms endometriosis in the posterior cul-de-sac but does not provide details on whether it is superficial or deep infiltrating. This often occurs with initial diagnoses or when surgical pathology reports do not specify the depth of invasion. Supporting documentation includes operative reports, pathology reports, and physician notes detailing the location of endometriosis.

• Do not use this code if the documentation specifies superficial (N80.3A) or deep infiltrating (N80.3B) endometriosis of the posterior cul-de-sac.
• Always review operative and pathology reports for specific depth information to ensure the most precise code is selected.
• Consider sequencing this code after any codes for associated infertility or chronic pelvic pain, if applicable and documented as primary reasons for the encounter.
